中文摘要:
      祁连泽里地区基性—超基性岩较发育,具有形成岩浆型硫化物镍钴矿(化)体的地质条件。由于研究区地表覆盖较厚,本次工作结合区域地质、物化探特征,在其所圈定的镍钴成矿有利地段开展了以地面高精度磁测和激电中梯为组合方式的综合物探找矿应用研究。利用地面高精度磁测来圈定区内基性—超基性岩分布,研究其磁性特征、异常展布规模并配合激电中梯剖面测量成果,提出一套寻找超基性岩镍钴矿的方法组合。此次成果表明找矿方式效果显著,对同类地质成矿背景的隐伏镍钴多金属矿勘查工作具有一定的参考价值。
英文摘要:
      The basic-ultrabasic rocks are well developed in Zeli Qilian, and they have the geological conditions for forming magmatic sulfide nickel-cobalt ore bodies. Due to the thick surface coverage of the study area,combined with regional geological and geophysical characteristics, in the nickel-cobalt metallogenic favorable area delineated by it, the comprehensive geophysical prospecting application with the combination of surface high-precision magnetic survey and IP intermediate gradient has been carried out. The distribution of basic-ultrabasic rocks in the area is delineated by high-precision magnetic survey on the ground. Its magnetic characteristics and anomalous distribution scale are studied, and the prospects of ore-bearing rocks are predicted with the results of IP intermediate gradient profile survey. The results show that the prospecting method has remarkable effect and has certain reference value for the exploration of concealed nickel-cobalt polymetallic deposits in the same geological and metallogenic background.
